Designated Investigation Agency | Voluntary Investigation to Prevent Development Stagnation Due to Soil Contamination | Geotech

To prevent development setbacks due to soil contamination before purchasing land, we propose buyer-led historical investigations and voluntary Phase 2 sampling for risk mitigation.

This is a solution that explains the comprehensive voluntary soil contamination investigation conducted by the buyer to prevent business setbacks caused by "soil contamination," which is the greatest potential risk in land transactions and real estate development. Rather than relying solely on information disclosure from the seller, the investigation aims to ensure safety before land purchase, starting with Phase 1, the "Buyer-side Historical Investigation," which thoroughly uncovers the history of past use of specific hazardous substances and the potential for underground infiltration. If further risks are a concern, a "Voluntary Phase 2 Investigation" will be conducted on-site, where soil gas and sample sampling, along with official analysis, will quantify the presence and concentration of contamination as scientific evidence. This approach effectively avoids critical development risks such as unexpected contamination discoveries leading to delays in construction schedules or business setbacks after the commencement of construction work. In the event of contamination being discovered, it is also possible to calculate countermeasure methods and purification costs in advance, allowing for advantageous negotiations regarding warranty clauses and price adjustments in the sales contract. We provide high-precision investigation services unique to designated investigation agencies that support asset value preservation and safe real estate investment.

Designated Investigation Agency | Soil Investigation of Narrow Sites and Operating Buildings | Geotech

Even in narrow sites with existing buildings or operating factories, the buyer's independent investigation using specialized small drilling equipment will identify soil contamination risks in advance.

This is a self-investigation solution designed to accurately assess soil contamination risks while maintaining existing factory buildings or structures on operational sites, or in narrow urban areas where large machinery cannot access. Typically, general environmental surveys assume that the site will be cleared, but decisions regarding land purchases and demolition budgets need to be made before contracts are signed, and waiting for the site to be cleared would not meet business timelines. Our service first identifies the past layout of machinery and the locations of hazardous material handling pits within existing buildings through a "buyer-side historical investigation," accurately narrowing down areas of contamination concern. In the subsequent sampling process, we utilize our own ultra-compact and simple drilling machines that can operate in low-ceilinged interiors and narrow corridors, completing a "voluntary Phase 2 sampling investigation" precisely without disrupting operations. This unique technology allows for a reliable understanding of underground contamination conditions and development risks while leaving the buildings intact before purchase.

Designated Investigation Agency | Favorable Land Price Negotiation through Voluntary Soil Investigation | Geotech

To avoid making mistakes in the decision to purchase land and to maintain negotiation leverage with the seller, we propose thorough due diligence and sampling on the buyer's side before the contract as a reliable risk management strategy.

This is a strategic soil contamination self-investigation solution developed for real estate investors and M&A practitioners, aimed at fully grasping the sovereignty of land transactions and achieving contract agreements under favorable conditions. In real estate deals, the unseen underground contamination risk is the greatest uncertainty, and if not addressed, the buyer will bear the burden of significant additional costs or development risks due to construction halts after purchase. This service strategically prioritizes "buyer-side historical investigations" during the assessment period before contracts, thoroughly evaluating the likelihood of contamination based on the land's past usage history. Furthermore, if risks are detected, an "independent Phase 2 sampling investigation" is immediately conducted to establish scientific and irrefutable numerical evidence based on official analysis. Armed with this data, buyers can engage in powerful price reduction negotiations with sellers and incorporate strict warranty clauses into contracts, thereby maximizing investment safety and dramatically increasing the overall win rate of the deal.

Designated Investigation Agency | Early Soil Contamination Survey During Operations When Rebuilding Automobile Maintenance Factories

To prevent delays in construction during factory rebuilding and facility decommissioning, we propose an early soil contamination survey to clearly identify potential risks around the equipment from the operational stage.

This proposal is an early soil contamination survey package aimed at owners, management, and general affairs departments of currently operating automobile maintenance factories, designed to clarify potential risks on-site without halting operations. In maintenance factories that have been in operation for many years, there is a risk that cleaning solvents such as trichloroethylene, which fall under specific harmful substances, as well as lead, hexavalent chromium, cadmium, boron, and fluorine from past soldering, putty polishing, and anti-corrosion chromate plating processes, may have permeated underground from aging pipes and pits. If these issues are left unaddressed and the factory faces reconstruction or the closure of specific facilities, there could be unexpected high-cost construction and significant delays in the schedule. As a designated investigation agency by the Ministry of the Environment, we provide comprehensive support for planned environmental risk management and cost reduction, from detailed historical verification of the factory's operational history to narrow-site and indoor sampling using a completely electric simple boring method (SCSC method) with zero exhaust emissions, depth-specific boring surveys to narrow down the three-dimensional extent of contamination, and rapid public analysis of leftover soil from reconstruction.

Natural origin heavy metal pollution soil insolubilizing agent (RE)

Safe solidification treatment technology for effectively utilizing construction-generated contaminated soil as construction materials: 'Solidification agent for naturally derived heavy metal contaminated soil using gypsum powder and scallop shells.'

Natural origin heavy metal contamination soil immobilization agent (RE) is an immobilization agent for naturally occurring heavy metal contaminated soil generated at construction sites such as tunnels, rivers, roads, and dams. It is a calcium-based immobilization agent primarily composed of scallop shells and gypsum powder. By adding this immobilization agent (soluble) to the contaminated soil, a reaction layer with a high concentration of calcium is formed on the surface of the soil particles (a site that promotes the immobilization reaction). This reaction layer efficiently immobilizes the heavy metals and suppresses their leaching from the contaminated soil particles.
